The insulated pipe 4 is sleeved over the water pipeline, forming an insulation chamber between the insulated pipe 4 and the water pipeline. A heating assembly is mounted on the outer wall of the insulated pipe 4 via the mounting assembly. The heating assembly is connected to the insulation chamber and heats water to generate steam. This steam enters the insulation chamber to heat and insulate the water pipeline. The water replenishment assembly is used to replenish the required water to the heating assembly.

[0029] In some embodiments, the heating assembly includes a heating box 5, a heating rod 7, a temperature sensor 14, and a controller. The heating rod 7 and the temperature sensor 14 are both connected to the controller. The heating rod 7 is fixedly mounted on one side of the inner wall of the heating box 5. The interior of the heating box 5 is filled with a portion of water. The outer wall of the heating box 5 is connected to a water replenishment assembly. The temperature sensor 14 is fixedly mounted on the top of the heating box 5. The temperature sensor 14 can detect the temperature information of the external environment. The controller obtains the temperature information and compares it with the internal preset temperature threshold. If the temperature information is lower than the preset temperature threshold, the heating rod 7 is controlled to heat the internal water. Specifically, an inspection cover 15 is hingedly mounted on the top of the heating box 5. By opening the inspection cover 15, the interior of the heating box 5 can be maintained and repaired.

[0030] Furthermore, a baffle plate 8 located above the water body is provided in the heating box 5, and a plurality of steam holes 9 are provided on the baffle plate 8. The outer wall of the heating box 5 is connected to the insulation pipe 4 via a steam pipe 6. One end of the steam pipe 6 is connected to the outer wall of the insulation pipe 4, and the other end of the steam pipe 6 corresponds to the chamber above the baffle plate 8.

[0031] When the water inside the heating box 5 is heated to boiling, the blocking plate 8 can be used to block the boiling water and prevent it from entering the insulation tube 4. At the same time, water vapor can enter the insulation tube 4 through the steam hole 9.

[0032] In some embodiments, the water replenishment assembly includes a water inlet pipe 10 and a solenoid valve 11. One end of the water inlet pipe 10 is connected to the heating assembly, and the other end of the water inlet pipe 10 is connected to the water pipeline.

[0035] The implementation principle of an antifreeze device for a water pipeline is as follows:

[0036] The insulation pipe 4 is sleeved on the outer wall of the water pipeline. When encountering severe cold weather, the water inside it is heated by the heating rod 7 in the heating box 5. After the water is heated, steam is generated. The steam enters the insulation pipe 4 through the steam pipe 6, and the water pipeline is heated by the steam, thereby preventing the water pipe from freezing in winter. The combination of steam and the insulation pipe 4 can extend the insulation time on the one hand, and heat and prevent freezing of long-distance water pipes on the other hand.

[0037] The above are all preferred embodiments of the present invention, and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
